Engineering Selection Recommendations

Direct Substitutes (Same Footprint - 10.00mm Diameter):

UUB1A331MNL1GS and UCJ1A331MCL1GS are direct Nichicon substitutes with identical land size and diameter. UUB1A331MNL1GS provides doubled lifetime (2000 Hrs vs 1000 Hrs) with no other parameter changes. UCJ1A331MCL1GS offers increased ripple current capacity and extended lifetime but has a 0.019" (0.50mm) height increase and specified ESR of 1.5 Ohm.

EEE-TG1A331P (Panasonic) matches the 10.00mm footprint with AEC-Q200 automotive rating and 2000 Hrs lifetime. EEE-TK1A331P extends lifetime to 3000 Hrs with lower ESR (200 mOhm @ 100 kHz) and maintains the 10.00mm footprint. EEE-TP1A331AP provides the highest ripple current capacity (325 mA @ 120 Hz, 500 mA @ 100 kHz) with 3000 Hrs lifetime and AEC-Q200 rating.

Compact Substitutes (8.00mm Diameter):

EEE-TG1A331UP, EEE-TK1A331UP, and EEE-TPA331UAP use 8.00mm diameter packages with 8.30mm x 8.30mm land size. These require PCB layout modification. All three maintain 10 V, 330 µF specifications and ROHS3 compliance. EEE-TK1A331UP and EEE-TPA331UAP both provide 2000-3000 Hrs lifetime with AEC-Q200 rating where applicable.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance, MSL Level 1, and REACH unaffected status. Panasonic automotive-grade parts (EEE-TG, EEE-TP series) carry AEC-Q200 certification. Selection between general purpose and automotive grades depends on application requirements and supply chain specifications.

Frequently Asked Questions (FAQ)

Q: Can EEE-TG1A331UP replace UWH1A331MCL1GS directly on the PCB?

A: No. EEE-TG1A331UP uses an 8.00mm diameter package with 8.30mm x 8.30mm land size, while UWH1A331MCL1GS uses 10.00mm diameter with 10.30mm x 10.30mm land size. PCB layout modification is required.

Q: What is the difference between UUB1A331MNL1GS and UWH1A331MCL1GS?

A: Both are Nichicon 330 µF 10 V capacitors with identical footprints and electrical specifications. UUB1A331MNL1GS has doubled lifetime rating (2000 Hrs vs 1000 Hrs @ 125°C). All other parameters remain unchanged.

Q: Why do some parts list ESR and others show a dash?

A: ESR is provided only when specified by the manufacturer. Parts without ESR values listed do not have this parameter defined in the datasheet. When ESR is critical for application performance, select parts with specified ESR values.

Q: Are Panasonic EEE-TG and EEE-TK series compatible with Nichicon UWH series?

A: Yes, for parts with matching 10.00mm footprints (EEE-TG1A331P and EEE-TK1A331P). Both maintain 330 µF, 10 V, ±20% tolerance, and identical land sizes. Panasonic parts offer extended lifetime and lower ESR specifications.

Q: What does AEC-Q200 rating mean?

A: AEC-Q200 is an automotive qualification standard. Parts with this rating are qualified for automotive applications and have undergone additional reliability testing. Selection depends on whether the application requires automotive-grade components.

Q: Can I use EEE-TP1A331AP in place of UWH1A331MCL1GS?

A: Yes, for direct PCB substitution. Both use 10.00mm diameter with 10.30mm x 10.30mm land size. EEE-TP1A331AP provides superior ripple current handling (325 mA @ 120 Hz vs 112 mA) and extended 3000 Hrs lifetime with AEC-Q200 automotive certification.

Q: What is the height difference between UWH1A331MCL1GS and UCJ1A331MCL1GS?

A: UWH1A331MCL1GS has maximum seated height of 0.394" (10.00mm). UCJ1A331MCL1GS has maximum seated height of 0.413" (10.50mm), a difference of 0.019" (0.50mm). Verify clearance in the application before substitution.
